I was doing the poor man compression test check and I have a question. The front rotor is a steady CH-CH-CH-CH-CH sound while the back is a ch-ch-CH-ch-ch-CH-ch-ch-CH, I read that the front rotors on s4's push more air while the rears do on s5's for reasons unknown , is this what I am experiencing or is my rear rotor fubar'd

sounds like a damaged apex seal on the rear rotor.

That is the sound of two missing compressions; from a broken or stuck apex seal.
Rebuild it.

Think about it dude... the apex seals sit on the APEX of the rotor... that means that each seal is responsible for two sides of the rotor.

If you lose 1 apex seal, its gonna blow the compression on two sides of the rotor.

you have two good seals, the only side of the rotor that is making compression is between those two seals.

Don't **** around.. if the seal hasn't damaged the rotor housing already, it sure as hell will if it comes apart and drags around in there. Once they are nicked, they are done....

engine kits cost 550 to 875 depensing on what you get with the kit.. New rotor housings are 475 EACH!!

Solution: Atkins Rebuild kit (and 3 MM apex seals too!)
